L052fil fill, Specincati T 0 all whom, it may concern Be it known that l, Bonner HENRY Jin complete separation of metals carrying valuse from their ores or gangue in which they are contained, may be economically effected.

The present invention relates more par,- ticularly to certain improvements in the apparatus described and illustrated in my pending application, serially numbered 550,703 and filed March 21, 1910, in which provision is made for giving the surface liquid in a containing tank or ves el, motion fromthe center thereof, outward to an overflow at the periphery and further for delivering and distributing the dry metallic particles, in a finely divided state, over the various surface of the liquid, to effect a separation by the method above referred to. In my prior application, the means. disclosed for imparting motion to the surface liquid in the tank, is shown and described as a rose nozzle, fitted to the outlet end of a liquid supply pipe and relatively arranged to discharge the liquid laterally in all directions. T have found that by modifying the construction and arrangement of the rose nozzle, better results are obtained and to this end, I cap the same in manner to direct the liquid downward at a suitable angle and then direct it laterally by means of a conical disk deflector, which. may be adjusted relatively to the nozzle, conditions may require.

The accompanying drawings will serve to illustrate apparatus suitable for carrying my invention into effect. I wish it understood, however, that I do not limit myself to the exact construction or arrangement of parts shown and described, as various changes may be made within the meaning ofthe present invention.

Referring now to the drawings, 1 represents a liquid containing tank or vessel in the form of an inverted cone. A water pipe 2, from any suitablesource of supply, terminates in branches 3 and 4, which are run into the tank and arranged to deliver at points at or neauthe bottom and top thereof. The branch 3, delivering at the bottom of the conical tank, may be tangentially disposed therein, turned upward or otherwise arranged to maintain suificient force or in-rush, to act as a cushion to prevent the ore settling too rapidly toward the outlet valve 5, and at the same time keep the water in the tank at a proper level. The

water intended to float the metallic partielse, is supplied by the branch 4, which terminates ust above the surface of the liquid in the tank, in a nozzle 6, shaped to discharge a circular jet. The nozzle 6,-is capped as indicated by an approximately semispherical shell 7, which serves to direct the circular et from the nozzle,- downward at a suitable angle and it is thereafter de-\ :tlected outward, in the plane of the surface of the liquid in the tank, by a conical disk -8. By means of a screw-thread connection JIlCllCiLiQCl at 9, the conical disk 8 may .be

adjusted relatively to the circular jet, as

conditions may require. The screw threads may be formed directly on the branch pipe lor as indicated on a sleeve 10, inclosing the pipe.

Mounted above the tank 1, there is a hopper 11, preferably of inverted cone=shape, having an outlet 12 at the bottom, which 1s controlled by a valve 12. The valve 12 is mounted on a 'shaft13, which, is geared to be driven-by a belt pulley 14. on a shaft 15. The rationing and closing of the valve is controlled by a hand-wheel 16 on shaft '17. l

ne construction and arrangement of the gearing, shaftmg, etc., for rotating and controlling this valve is fully described in my.

prior application referred to and as the same is not claimed herein, 1t Wlll not ,be further described.

In the use of the apparatus, the ore is fed to the hopper 11, from which it is dis-' In the operation of the apparatus, the surface of the liquid in the separator is given a'conical form by the disk 8 and through the arrangement of the conical spray device 6-7, a constant flow is maintained radially.

outward in all directions. The finely divided ore, falling thereon, is quickly and rapidly disposed of, the lighter valuable particles being carried outward to the periphery of the tank, thereto be collected in a launder 18, and thereafter settled by suitable means, while the heavy coarse'metallic particles together with barren material, sink through the water to the bottom of the tank and may be drawn off through the valve and subsequently treated. This result is obtained only when there is an even distribution ofv the-ore upon the conical surface of the liquid in the tank and further, as ore differs materially, the result is also dependent more or less upon the angle at which the particles strike the surface. The skipping of the stones over the surface of water may be cited as illustrating this last mentioned action, since unless thrown at the proper angle, stones .both light and heavy will be driven below the surface.

The important advantages of the peculiar feeder herein disclosed will be apparent. In addition to effecting equal distribution of the ore particles over the surface of the liquid in the separator tank, it is adjustable vertically to permit the angle of fall of such particles to be varied as may be required, depending upon the particular run of ore being separated.

Itis found that the addition of a small percentage of oil or saline solution to the water in the tank, causes the metallic particles in certain cases to float more freely and in such instances, may be usedto advantage. It is also found that the use of liquids heavier than water in some cases, increases the extraction. C

Having, therefore, described my invention, I claim:

1. An ore-float separator containing a body of liquid, means giving the eli'ective surface of the liquid conical form, a centrally disposed liquid supply delivering the liquid radially outward in all directions, an ore distributor above the liquid and adjustable to and from the liquid surface, means for imparting rotary motion to the ore distributor.

2. An ore-float separator containing a body of liquid, a conical member rising from the surface of the liquid, means maintaining a flow of liquid radially outward in all directions over the surface of the conical member, an ore distributor above the member and adjustable to and from said member to vary the angle of impingement, and means for imparting rotary motion to the ore distributer.

3. An ore-float separator containing a body of liquid,aconical member rising from the surface of the liquid, means maintaining a flow of liquid radially outward in all directions over the surface of the conical member, a valved hopper above the member, and means for simultaneously rotating and adjusting the valve, said hopper and valve being slightly above the flowing liquid, and said valve adjustment being adapted to vary the angle of impingement of material upon the flowing liquid.

4. An ore-float separator containing a body of liquid,aconical member rising from the surface of a liquid, means maintaining a flow of liquid radially outward in all di-' rections over the surface. of, the conical member, a valved hopper above the memher and slightly spaced therefrom, a shaft carrying the valve of the hopper and means for simultaneously imparting rotary and longitudinal motion to the shaft and the valve carried thereby.
